This invention relates to improvements in va An object of the invention is to provide av combined storm and screen sash unitwith the sash of sliding type readily applicable to an installed window frame, furnishing either insect or storm protection, the latter auxiliary to the reg ular light sash with which the window frame is ordinarily equipped, and avoiding the necessity of removal or replacement of either of the auxiliary sash of the unit for different seasonal service.

Another object is `to provide a 'sheet metal frame and sash unit, the sash slidably sustained and readily removable from the frame for auxiliary service and readily applicable within an installed conventional window frame.

Variousv other features and advantages will be more fully set forth in the description of the accompanying drawings, in which: f

The seasonal substitution or replacement of the storm and screen sash, requiring the alternate storage of one while the other is in use, has always been of considerable annoyance to the user, and the removal of the storm sash during the warm weather period provides no auxiliary protection for the window in an emergency during a heavy rain or windstorm.

It has been the common practice to employ separate storm and screen sash to take in the full measurement of a window frame, necessitating their removal in making a seasonal change from one to the other. A single sash accommodating for the full opening area of a window `frame is burdensome to handle and requires to be hinged to adapt the same to be swung outwardly to obtain access to the main sash for cleansing, and it is generally necessary to remove the auxiliary storm sash for cleansing as its outer side usually is not accessible from the window opening.

The auxiliary sash are slidably sustained in sheet metal rails of suitable length for a given size of window opening, respectively individually -and styles of window frames.'

Referring to the drawings, I indicates a pair of sheetmetal side rails or guides in separate or individual length and respectively removably secured to the .lambs 2 of the window or sash frame preferably along the outer side of the outer blind stops or bead strips 3 as a part of the window frame. The rails, either as separate strips or the sides of a frame. are of duplicate construction, formed of sheet metal, primarily of Z cross section for its entire length providing a pair of oppositely extended flanges 4 and l at relative opposite sides and ends of the central web portion. The flange 4 is provided with a plurality of notches or apertures 9 extending laterally inward from its longitudinal edge and at a definite spacing apart, each for the reception of a screw 'I for adjustablysecuring the rail to a blind stop 3 of the window frame. The rail is adjustable on blind stop or can be set to accommodate for an appropriate width of sash and to bring the inner side of the web portion of the rail approximately y flush with the face side of the outside blind stop.

as shown in Figure 5, or slightly therebeyond to avoid interference in theinsertion or removal of the auxiliary sash.

The flange 5 of the rail, as an outside stop, extends inwardly of the window frame and has its longitudinal margin 9 inturned, rounding the edge and reinforcing the flange. The ange for an approximate length of the upper storm or auxiliary sash 9 has its inturned margin 9 slightly spaced from the portion of the flange which it overlies to provide a yielding bearing surface against'the frame of the upper auxiliary light or storm sash 9 to effect a weather seal. The inturned margin 8 for the length of the lower sash is compressed or clinched against the flange 5 which it overlies, as no yielding influence is required for effecting a weather seal. as it .provides an outside stop strip for a screen sash I0. The double ply formation of the front flange for the length of the lower sash thereof accommodates for a slightly greater thickness of conventional screen frame over the conventional frame material employed for the light sash, thereby bringing the top and bottom sash or frames flush with each other at the inner side.

The sash sustaining rails for the major portion of the length occupied by the lower sash correspondingly are formed to provide a channel to accommodate and laterally confine a pair of auxiliary sash, as the screen sash II and the second lower light sash. The channel formation is produced by various methods, as by folding a section of the main rail upon itself and bending the same at an angle to the web portionto'form a double ply inturned guide flange or inside stopII with the outer limb thereof co-extensive, or as a continuation of the anchoring flange of the rail according to one mode of rail manufacture as illustrated in cross-section Figure' 6.

A secondary rail section I2 is fitted within and constitutes a part of the main rail for the length of the lower sash and comprises a strip of sheet gitudinally for the length of the secondary raIl within the channel section of the rail and with the flange II of the rail forms a groove for the lower light sash. The upper end of the limb I3 also serves to support the upper sash.

Ina modified form of secondary rail section, shown in cross-section Figure 14, the rail section mainly is of channel form in cross-section with the web portion ofl'set or stepped longitudinally to provide a longitudinal guide shoulder I5. The

. inner flange I8 of the secondary rail is doubled back upon itself to laminate the same, and the outer lamination is co-extensive with and underlies the anchoring flange 4 of the main rail. In the form shown in Figure 17, corresponding in part to that shown in Figure 6, the outer 'flange I I represents a separate strip fixed to the underside of the anchoring flange 4 of thev rail.

Each guide rail fory the upper section of the vwindow frame or upper auxiliary sash is of nonchannel form and thereby is open to one or the inner side for the insertion and removal of all of the sash of the unit, while the lower section is of channel form and laterally confines a pair of sash disposed therein.

The upper sash 9 at each of its opposite lowerA corners has a lug I1 depending therefrom for intermesh or engagement into a notch I9 formed in the top end of the limb I2 of secondary rail section I2 to normally latch the lower end of the upper sash 9 against a lateral displacement, as shown in Figures 9 and 10. The upper end of the upper sash 9 is engaged within the channel of a channel cross rail I9 xed to the head of the window frame. The cross rail I9 has its opposite ends cut to outwardly overlap the relative ends of the adjacent outer limb 5 of the vertical rails to provide a weather sealing corner Joint. The channel of the upper cross rail has a depth sufll-l cient to allow the upper sash to be 'elevated to a degree to release it from its latching connection with the side or vertical rails whereupon it can be swung outwardly for removal from the rails.y

The screen sash I 0 is inserted or removed from the upper section of the side rails and normally is positioned within the low er channel portion thereof immediately beneath the upper sash. with the inner side of the screen frame flush with the frame of the upper sash. As the opposite ends of the screen sash adjoin the offset portion of the channel to provide a guideway for the inner second lower sash 20, the width of the screen sash is Lslightly less than that of the upper sash.

The second lower sash 20 has its opposite ends engaged and slidable within the guideway or groove formed in the lower section oi' the side rails to guide in elevating the sash for removal or to station it to an open position in an adjoining relation with the upper sash, as shown in Figures 2 and 8. 'Ihe second lower sash in either its closed or open position confines the screen sash against a lateral displacement so that no other means need be employed' toy hold the same in place while in service.

The lower auxiliary light or storm sash at its lower end is provided with a finger holdl and at each of its opposite ends respectively with a latch 2| shown as of slide bolt typeI The type of locking hardware, however, is optional. The outer end of each lock bolt 22 of the latches 2l in its locking position :overlaps the outer side of its relative inner limb orinside stop II of a side rail and in its locking position frictionally contacts therewith for holding the sash in any parrail, to function substantially as the top rail secing from the inner side of the web of a rail for a lower section thereof relatively spaced from and parallel with said second flange and with the web portion of the rail providing a channel for the reception of an adjacent pair vof sash, a light sash sustained within the upper section of the rail and locked thereto,l a screen sash for the lower section immediately beneath the upper light sash, and a second light sash for the lower section adjoining said screen sash and adapted to be elevated within the rail and locked thereto in an elevated pofsition.

2. For mounting on a conventional window frame provided with outer blind stops, a sheet metal rail fixed to one of said blind'stops of Z form in cross section providing relatively offset oppositely extended flanges longitudinally of therail, one for anchoring the rail to said blind stop, and the second providing an outside stop tion I9 previously described. A channel form-l of cross or sill rail connects with the lower ends of the side rails I into which the lower end of both screen and storm sash I0 and 2B respectively seat.

The frame structure for the upper and lower auxiliary or storm sash, preferably is of conventional sheet metal strip material of, channel form type which clasps over the edges of a pane of glass and provides for a minimum thickness of frame, approximately one quarter of an inch,

' sufilcient to furnish the necessary stability. This also follows for the structure of screen frame as representative of a conventional type of manufacture, having at one side a channel into which the screen fabric is clinched by a channel form of beading or clipping strip.

For individual application the vertical and cross rails are made up in stock lengths easily cut and trimmed for a length measurement of a given size frame which likewise follows for the sheet metal strip material for the light and screen frames, so that fabrication and installation is extremely simple and inexpensive.

Normally the aligned upper light and lower srceen sash remain stationary in their relatively located positions within the guide or side rails and generally are only removed to gain access to the exterior side of the main sash, should the main sash be of sliding type. 'I'his also follows for the second lower auxiliary light sash which, however, is slidably sustained and located inA an elevated or open position, in which position it remains during the summer season and serves to bind the screen frame against lateral displacement within the side rails. The second or lower auxiliary light sash in its normally full open, elevated position has a sufficient portion of its lower end engaged within the channels of the side rails to withhold the same against outward tilt so that no means need necessarily be included for holding the upper end of the sash against lateral displacement. The lower light sash, however, must be rst removed before it is possible to remove the screen sash.

. and the second providing an outer bead for conlining an auxiliary sash disposed within said rails against outward displacement, a flange projectfor confining an auxiliary sash disposed within said rail against outward displacement, a flange for the lower section of the rail providing an inside stop, a light sash sustained within the upoutside stop and locked to the rails, a screen sash l for the lower section immediately beneath the upper light sash, and a light sash for the lower section adjoining said screen sash. and adapted to be elevated within the rail and locked thereto in an elevated position.

3. For mounting on a conventional window frame provided with outer blind stops, a sheet metal rail fixed to one of said blind stops of Z form in cross section provid-ing relatively offset opposltely extended flanges longitudinally of the rail, one for anchoring the rail to said blind stop, and the second providing an outside stop for confiningan auxiliary sash disposed within said rail against outward displacement, a flange for the lower section of the rail providing an inside stop, a light sash sustained within the upper section of the rail in bearing contact with said outside stop and locked tothe rail, a channel rail fixed to the head of the window frame for clasping and confining the upper end of the upper sash, a screen sash for the lower section immediately beneath the upper light sash, and a light sash for the lower section adjoining said screen sash and adapted to be elevated withinl the rail and locked thereto in an elevated position.

4. For mounting Von a conventional window frame, a sheet metal rail fixed to one of the sides of the window frame of Z form in cross sec:

tlon providing relatively offset oppositely extended flanges longitudinally of the rail, one for anchoring the rail to the window frame, and the second providing an outside stop for confining an auxiliary sash disposed within said rail against outward' displacement, a flange for the lower section of the, rail providing an inside stop, a light sash sustained within the upper section of the rail and in bearing contact with said outside stop, a screen sash and a light sash in o adjoining relation for the lower section, the' screen sash immediately beneath the upper light sash and said lower light'sash adapted to be elevated within the rail and locked thereto in an elevated position.

5. A storm sash and frame unit for ready application within a conventional window frame, comprising: a frame having side and top rails each of Z form in cross-section, providing an outer flange for applying the frame to a conven- I tional wlndowfframe and an inner ange provldfor the -lower sash portion o! the rame forming ing an outer stop for the sash -sustained within a. channel for glldnbly mounting the lower sash, theA frame, an upper sash laterally removable ladapting the seme to be elevated for removal from the frame and adapted to be locked therein. from the frame. from the 'upper sash portion and a. screen'and light sash relatively adjacently 5 lthereof. disposed within the lower section of the :rame with the screen-sash outermost. the slde ralls LELAND T.
